[0094] In the exemplary embodiment, the discrete catheter assembly 1 is generally constructed with the following major components: a containment unit and an outer protector layer.

[0095] As assembled, the catheter 10 is inserted into the holding vessel passageway 20c at holding base member 24 and extending the length of the holding vessel 20. One of ordinary skill in the art would understand the applicant's design is not the exclusive embodiment.

[0096] In the exemplary embodiment, the catheter 10 is inserted through the holding head member 26 and the retainer opening of the retainer 40. One of ordinary skill in the art would understand the applicant's design is not the exclusive embodiment. The combined components are inserted into the shell passageway 30c of the shell 30. The dispenser 50 is then positioned to the shell head 34. One of ordinary skill in the art would understand the applicant's design is not the exclusive embodiment.

[0097] In the exemplary embodiment, the catheter 10 is then inserted into the dispenser passageway 50c where the retainer 40 is positioned between the rear face 50b of the dispenser 50 and the holding head member 26. One of ordinary skill in the art would understand the applicant's design is not the exclusive embodiment.

[0098] In the exemplary embodiment, the rear cap 70 is fitted over the shell base 36 in, which the cap raised groove 76 is adjacent to the raised groove 38 of the shell base 36. One of ordinary skill in the art would understand the applicant's design is not the exclusive embodiment. Lastly, the front cap 60 is inserted over the dispenser 50 and secured to the shell head 34 by the raised groove 38 of the shell head 34.

[0099] When the assembly is ready to be used, the front cap 60 is removed allowing the dispenser 50 and specifically the distal tip 58 to be exposed.

[0100] In a neutral state, the retainer 40 is angled and is not in contact with the biasing surface 54, which allows for the catheter 10 to freely move in a first direction S as shown in FIGS. 29-35.

[0101] In an active state, the rear cap 70 is pulled in the first direction S extending the holding vessel 20 towards the shell base 36 of the shell 30. The flaps 29 of the holding vessel 20 engage and become flush with the plurality of rectangular protrusions 39 using the edge L, which allows the holding vessel 20 to glide and move freely.

[0102] The holding head member 26 makes contact with and becomes flush to an outer rim of the projecting base 14 of the catheter 10. The holding head member 26 continues to move as it passes over the projecting base 14 of the catheter 10 in the first direction S until the holding head member 26 is stopped by the free-floating circular ring 37 located on the inner face 30b of the shell base 36. Once the holding head member 26 has been stopped by the free-floating circular ring 37, the holding vessel 20 is fully extended as shown in FIGS. 37-44.

[0103] The rear cap 70 is then pushed in a second direction N where the circular cradle 28 makes contact with and nestles a rear of the projecting base 14 of the catheter 10 while continuing to move in the second direction N until the projecting base 14 makes contact with the retainer 40 as shown in FIGS. 45-48.

[0104] The retainer 40 is then angled perpendicular to the assembly. Further, the first face 40a of the retainer 40 is in contact and flush against the biasing surface 54 to maintain stability of the catheter 10 while a fluid is received. The catheter 10 travels through the dispenser passageway 50c and penetrates the distal tip 58 of the dispenser 50.

[0105] The fluid is then received through the eye slits 18 of the catheter 10. The fluid travels through the tube passageway and exits the catheter 10 through the projecting base 14 and into the holding vessel 20. The assembly 1 permits fluid communication between the distal and proximal ends and allows the fluid to be released and drained when the rear cap 70 is removed as shown in FIGS. 49-50.

[0106] In an alternative embodiment, a bag (not shown) may be attached to the shell base 36 in order for the fluid to drain into the bag. One of ordinary skill in the would understand the applicant's design is not the exclusive embodiment.

[0107] The foregoing illustrates some of the possibilities for practicing the invention. Many other embodiments are possible within the scope and spirit of the invention. It is, therefore, intended that the foregoing description be regarded as illustrative rather than limiting, and that the scope of the invention is given by the appended claims together with their full range of equivalents.
